Field Summary
protected int capacityIncrement
The amount by which the capacity of the vector is automatically incremented when its size becomes greater than its capacity.
protected int elementCount
The number of valid components in this Vector object.
protected Object[] elementData
The array buffer into which the components of the vector are stored.

Constructor Summary
Vector()
Constructs an empty vector so that its internal data array has size 10 and its standard capacity increment is zero.
Vector(Collection c)
Constructs a vector containing the elements of the specified collection, in the order they are returned by the collection's iterator.
Vector(int initialCapacity)
Constructs an empty vector with the specified initial capacity and with its capacity increment equal to zero.
Vector(int initialCapacity, int capacityIncrement)
Constructs an empty vector with the specified initial capacity and capacity increment.
Method Summary
Appends the specified element to the end of this Vector.
Inserts the specified element at the specified position in this Vector.
Appends all of the elements in the specified Collection to the end of this Vector, in the order that they are returned by the specified Collection's Iterator.
Inserts all of the elements in the specified Collection into this Vector at the specified position.
Adds the specified component to the end of this vector, increasing its size by one.
Returns the current capacity of this vector.
Removes all of the elements from this Vector.
Returns a clone of this vector.
Returns true if this vector contains the specified element.
Returns true if this Vector contains all of the elements in the specified Collection.
Copies the components of this vector into the specified array.
Returns the component at the specified index.
Returns an enumeration of the components of this vector.
Increases the capacity of this vector, if necessary, to ensure that it can hold at least the number of components specified by the minimum capacity argument.
Compares the specified Object with this Vector for equality.
Returns the first component (the item at index 0) of this vector.
Returns the element at the specified position in this Vector.
Returns the hash code value for this Vector.
Returns the index of the first occurrence of the specified element in this vector, or -1 if this vector does not contain the element.
Returns the index of the first occurrence of the specified element in this vector, searching forwards from index, or returns -1 if the element is not found.
Inserts the specified object as a component in this vector at the specified index.
Tests if this vector has no components.
Returns an iterator over the elements in this list in proper sequence.
Returns the last component of the vector.
Returns the index of the last occurrence of the specified element in this vector, or -1 if this vector does not contain the element.
Returns the index of the last occurrence of the specified element in this vector, searching backwards from index, or returns -1 if the element is not found.
Returns a list iterator over the elements in this list (in proper sequence).
Returns a list iterator over the elements in this list (in proper sequence), starting at the specified position in the list.
Removes the element at the specified position in this Vector.
Removes the first occurrence of the specified element in this Vector If the Vector does not contain the element, it is unchanged.
Removes from this Vector all of its elements that are contained in the specified Collection.
Removes all components from this vector and sets its size to zero.
Removes the first (lowest-indexed) occurrence of the argument from this vector.
Deletes the component at the specified index.
Removes from this list all of the elements whose index is between fromIndex, inclusive, and toIndex, exclusive.
Retains only the elements in this Vector that are contained in the specified Collection.
Replaces the element at the specified position in this Vector with the specified element.
Sets the component at the specified index of this vector to be the specified object.
Sets the size of this vector.
Returns the number of components in this vector.
Returns a view of the portion of this List between fromIndex, inclusive, and toIndex, exclusive.
Returns an array containing all of the elements in this Vector in the correct order.
Returns an array containing all of the elements in this Vector in the correct order; the runtime type of the returned array is that of the specified array.
Returns a string representation of this Vector, containing the String representation of each element.
Trims the capacity of this vector to be the vector's current size.
